Ireland’s manufacturing sector maintained its expansionary momentum in September, with the AIB Ireland Manufacturing PMI inching up to 55.5 from 55.4 in August 2026.
The slight increase in the index, released with updated data on 1 October 2026, signals continued growth in Irish factory activity and keeps the PMI comfortably above the 50-point threshold that separates expansion from contraction. The back-to-back readings above 55 in August and September suggest that underlying conditions in the sector remain robust, even as the month-on-month improvement is marginal.
With the September 2026 figure marking a fresh high compared with the previous month, the data reinforce the view that Ireland’s manufacturing industry is sustaining a solid pace of expansion into the final quarter of the year.
